Quercus martinezii

Quercus martinezii is native to montane forests in the mountains of west-central and southern Mexico. It is found in the Sierra de San Juan of western Nayarit, the western Trans-Mexican Volcanic Belt of Jalisco, Michoacán, and Mexico states, and the Sierra Madre del Sur of Michoacán, Guerrero, and Oaxaca states.^[1]

The tree is generally found in cloud forests, and occasionally in humid oak forest and pine–oak forests, between 1,800 and 2,600 meters elevation.^[1]

The population size and trends of Quercus martinezii have not been quantitatively studied. Its observed populations are generally low-density or scarce. It is threatened with habitat loss from deforestation across much of its range.^[1] There are populations in several protected areas, including the Sierra de San Juan Biosphere Reserve in Nayarit, the Sierra de Manantlán Biosphere Reserve in Jalisco.
